EFFECT OF FLY-ASH AMENDED SOIL ON GROWTH OF LACTUCA-SATIVA L

The present study has been undertaken with a view to evaluate the impa ct of fly-ash amended soil on growth and photosynthetic pigments of La ctuca sativa L. It was seen that ten per cent treatment showed marked increase in plant growth while twenty and thirty per cent treated plan ts showed retarded growth as compared to control. Similar trend of inc rease and decrease in pigment formation was also observed. Results ind icate the utilization of fly-ash in low concentrations for better grow th, dry matter production and increased photosynthetic pigments.
